摘要

目前正在巴郎组和“青岛”组开展工作，以确定寒武系2第4阶段的合适候选基地。三叶虫分类学和地带性的修订，有助于揭示华南巴郎地区三叶虫新带的地层分布和地理分布。我们的研究结果表明，orytocarella duyunensis或Arthricocephalus chauveaui可能是很好的候选物种，因为它们也出现在北格陵兰岛Henson Gletscher组的eoaagnotus roddyi-Arthricocephalus chauveaui带。

Bioestratigrafía a partir de trilobites de las Formaciones de Balang y “Tsinghsutung” (Serie Cámbrica 2, Piso 4) en el área de Balang, Jianhe, Guizhou, China meridional

Ongoing work is carrying out in the Balang and “Tsinghsutung” formations to aim a suitable candidate for the base of the Cambrian Series 2, Stage 4. The revision of the trilobite systematics and zonation shed light about the stratigraphic distribution and the geographical distribution of the new trilobite-based zones in the Balang area (South China). Our results suggest that either Oryctocarella duyunensis or Arthricocephalus chauveaui could be good candidates since they also occur in the Eoaagnostus roddyi-Arthricocephalus chauveaui Zone of the Henson Gletscher Formation, North Greenland.
